Application filed February 8, 1919. serial No. 275,708.

county of Cook, State of Illinois, have invented certain new and useful Improvements in Eyeglass-Mountings, of which the following is'a specification.

This invention relates 'to e ye-glass and spectacle mounts in which the lens holding of shell or like non-metallic material, and either .bolly of such non-metallic material, or of a reinforced construction, and the present improvement has for its objects To provide a simple and efiective structural formation and association of parts whereby the nose bridge of the mounting is attached to the non-metallic lens inclosing ring in a strong and substantial. manner,

and which admits of a close pupillarity of the lenses being attained regardless of the thickness of said non-metallic'lens inclosing rm 'l o provide a simple and compact formation and combination of the connecting means between the adjoining ends of a split non-metallic lens holding ring affording a substantial attachment for the ring ends and a like substantial attachment of the members of said connecting means, all as will hereinaftermore fully appear; a

In theaccompanying drawingz- Figure 1, is a perspective view showing the general arrangement of parts of the present invention as,applied to a pair of spectacles.

Fig. 2 is a detail vertical section illustrating the connecting means heretofore referred to.

Fig. is a detail horizontal section illustrating theflconnection of the nose bridge .to the lens holding rings.

Fig. 4 is a detail sectional elevation of a modified form of the connecting means aforesaid.

Fig. 5 is a detail perspective view of the same.

Specification of Letters Patent.

"a detail I cross-section on line a'rch or bridge 1 connected to the rear of the.

continued forwardly form as an extension'12 adapted Patented Dec. 2, 1919 the usual archor bridge piece by which the lens holding members are fixedly connected together in properly spaced relation.

2 designates the pair of split'lens noldin'g members, which in the present construction. are each formed of an outer ring of nonmetallic material, such as tortoise shell, and an inner split metallic ring 3 acting as a reinforcement and grooved to receive the beveled margin'of an eye-glass lens 4. Said Inner ring 3 has a close fit in an annular groove formed in the ring 2, as shown and as usual in the present type of shell rim eyeglasses.

In the terminals of the lens engaging ring 3 at the split thereof, has outwardly disposed flanges or'extensions 5 which when the ring 3 is contracted to engage the lens 4L in an'assemblage of the parts, are in close contact to provide an extended and substantial "abutment between the ring ends or terminals. 6 designates clip pieces or tongues extendmg in angular relation from the outer ends of the aforesaid flanges or extensions 5an'd having approximately parallel relation to the main portion of the ring 3 and separated therefrom by a space corresponding to the thickness or cross-section of the nonpresent improvement the ends of metallic lens surrounding ring 2 as shown.

7 designate terminal prongs on the ends of the clip pieces 6 and adapted to be forced into recesses in the ring 2 to afford a simple and substantial connection'between' the inner and outer lens holding members 2 and 3.

8 designate plate extensions or ears brazed 'in their contracted condition upon the lenses 4:. p In the constructlon shown the plate extensions or ears 8 are formed with outer pivot ends for the pivotal connection of the'teniple bars 10 of a pair of eye-glasses or spectacles. v 11 designates rebent end portions 'of the lens holding rim 3 and in a curved to embrace the outer surface of the non-me tallic inclosing rim 2 and provide a rigid and substantial connection of the parts.

In the modified structure shown in Figs. 4, 5 and 6, the outer nonmetalli ring 2 is of a square form in cross-section, but in other details the construction is substantially identical with that described above in connection with Figs. 1, 2 and 3. In such modified structure the endsof the clip pieces 6 provided with lateral prongs 13 adjacent to the terminal prongs 7, with said prongs 13 adapted to be bent around the non-metallic ring 2 to embrace the same and afiord increased stability to the parts required in some special eye-glass structures.

Having thus fully described my said invention what I claim as nee and desire to secure by Letters Patent, is

1. In an eyeglass mounting, the combination of an outer split lens inclosing ring, an inner split lens holding ring arranged Within said outer ring and having outwardly ex tending flanges on its ends forming abutments for the ends of the outer ring, said flanges having at their outer ends angularly arranged clip tongues bearing against the outer face of the outer ring and provided with terminal prongs for engagement in recesses in said outer ring, and means for has teningsaid flanges together, substantially as set fort 1. i

2. In an eyeglass mounting, the'eombinetion of an outer split lens inclosing ring, an inner'split lens holding ring arranged within said outer ring and having outwardly extending flanges on its ends forming abutments for the ends of theouter ring, said flanges having at their outer ends angularly arranged clip tongues bearing against the outer face of the outer ring and provided with terminal prongs for engagement in recesses in said outer ring, plate metal members secured to said flanges and extending outwardly beyond the same, and fastening means extending through the outer ends of said plate members, substantially as set forth.
